Any GTK+ experts in the house?
In brief, we are running Ubuntu server on a single board computer. The software that we are writing uses GTK+ 2 for the user interface. The user interacts with the GUI via touchscreen.
We have a scrolling list of information in a table. The names in the table are big enough to easily select via the touch interface. However, the scroll bar is very narrow and it is hard to 'grab' it via the touch interface. Quite simply, we would like to make the scroll bar thicker.
Can we simply use a function like gtk_widget_set_size_request to change the geometry of the scroll bar or do we have to subclass the scroll bar widget and roll our own?
I am not the programmer so I apologize in advance if my question is not clear.
